Ethan Hawke is the latest star to urge fellow thespians to boycott the Oscars over lack of diversity.

“It’s going to take a few generations for them to really represent the community,” he said at DreamYard’s Bronx Writes’ Poetry Slam finals at Joe’s Pub on Tuesday night. “I got to sit next to Denzel Washington the night he won the Oscar [for ‘Training Day’], and Sidney Poitier was there, and Halle Berry won that night and it kind of seemed like all this was over. So, it feels . . . like the tide has gone out and pulled back in . . . So people need to shout. People need to be upset.”

Ethan and his wife, Ryan, were judges at the slam, which showcased poems from Bronx school kids.
